Figure 1.
Phase contrast images of RA-induced differentiation of SH-SY5Y cells after (a) 0 (Control), (b) 3, (c) 6 and (d) 9 days. Scale bar = 50 µm. (e) Changes in gene expression during 3, 6 and 9 days of differentiation of the SH-SY5Y cells. Principal component analysis plot of rlog transformed count data for the RNA-sequencing samples of 4 individual experiments (N = 4). Each replicate clusters according to their individual differentiation status. (f) Venn diagram showing overlap of differentially expressed genes between the different time points of differentiation of SH-SY5Y cells. Genes with FDR-adjusted p-value ≤ 0.05 and an absolute log2(fold change) > 1 were regarded as differentially expressed. Unprocessed phase contrast images are represented in Supplementary Figure S6.
